As mentioned in our Development Roadmap Part Two, the Kernel is the foundational layer of zeppelin_os, and we will soon be launching a prototype of it, starting with the functionality currently found in the OpenZeppelin framework.
We’re happy to announce another step towards launching the zeppelin_os Kernel. We’re now investigating different upgradeability mechanisms. As you may have read, there are several approaches to implementing contract upgradeability, like proxy libraries or eternal storage, among others. We’ve been working on a solution that combines some of these patterns.
